Immersion foot, left foot. This is a non-freezing cold injury resulting from prolonged exposure to cold and wet conditions.
The 7th character is required to indicate the encounter type: A (initial encounter), D (subsequent encounter), or S (sequela).
Medical necessity for treatment is established by the presence of signs and symptoms of immersion foot, such as skin discoloration, numbness, tingling, pain, and blisters. The severity of the condition and the potential for complications justify the need for medical intervention.
Physicians should document the duration and circumstances of the cold exposure, the appearance of the affected foot, and any associated symptoms like numbness, tingling, or pain.

In simple words: Immersion foot, also called trench foot, is a condition that affects the left foot. It happens when the foot is exposed to cold and wet conditions for a long time. This causes damage to the skin and tissues.
Immersion foot, also known as trench foot, occurs in the left foot due to prolonged exposure to a cold and wet environment. This condition is characterized by skin damage resulting from constricted blood vessels, reduced oxygen supply, nutrient loss, and toxin buildup.
Example 1: A hiker develops immersion foot in their left foot after trekking through wet and cold terrain for several days., A homeless individual experiences immersion foot in their left foot due to prolonged exposure to cold and rain without adequate footwear., A worker in a cold storage facility develops immersion foot in their left foot after accidentally spilling water on their boots and continuing to work in the cold environment.
Documentation should include the duration and nature of the cold exposure, the condition of the left foot (e.g., color, temperature, presence of blisters or ulcers), and any associated symptoms. Evidence of prolonged exposure to cold and wet conditions is crucial for accurate coding.
